Questions sur cet article

Will this 4GB DDR4 ECC SODIMM fit the DS2422+?

The module is listed as compatible with the 22 series DS2422+, so it fits that model.

How do I install the D4ES02-4G in my DS2422+, and what step is often missed?

Power off the NAS, open the chassis, insert the SODIMM at an angle until it clicks, then secure the retention clips; the step often missed is fully seating both clips.

When will the DDR4 ECC SODIMM need replacement in a DS2422+?

ECC memory rarely fails; replace only if the NAS reports memory errors or fails POST during boot.
